P71 axle seal Removal & Installation

If the vehicle is equipped with air suspension, the electrical power to the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the luggage compartment. Failure to do so can result in unexpected inflation or deflation of the air springs, which can result in shifting of the vehicle during these operations. Failure to follow these instructions may result in personal injury.

  1. If equipped, turn the air suspension service switch to the OFF position before raising the vehicle.
  2. Remove or disconnect the following

    Brake caliper and rotor
    Anti-lock brake speed sensor, if equipped
  3. Clean all dirt from the area of the axle housing cover.
  4. Place a drain pan under the axle housing.
  5. Remove or disconnect the following:

    Axle housing cover retaining bolts and the cover, draining the axle lubricant from the housing
    Differential pinion shaft lock bolt and the differential pinion shaft

  6. Push the flanged end of the axle shaft being removed toward the center of the vehicle
  7. Remove or disconnect the following:

    C-lock from the button end of the axle shaft
    Axle shaft from the housing, being careful not to damage the oil seal and anti-lock brake sensor ring, if equipped.
  8. Insert an axle bearing remover in the axle housing bore and position it behind the wheel bearing so the tangs on the tool engage the bearing outer race.
  9. Remove the wheel bearing and seal as an assembly using an impact slide hammer attached to the bearing remover tool

To install:
  1. Lubricate the new wheel bearing with rear axle lubricant.
  2. Install the wheel bearing into the axle housing bore using a bearing installer.
  3. Lubricate the lips of a new wheel bearing oil seal with wheel bearing grease.
  4. Install or connect the following:

    New wheel bearing seal using a seal installer
    Axle shaft into the axle housing without damaging the bearing/seal assembly or anti-lock brake sensor ring, if equipped. Start the splines into the side gear and push firmly until the button end of the axle shaft can be seen in the differential case.
    C-lock on the button end of the axle shaft splines, then push the shaft outboard until the shaft splines engage and the C-lock seats in the counterbore of the differential side gear.
    Differential pinion shaft through the case and pinion gears, aligning the hole in the shaft with the lock bolt hole
    Apply a thread locking compound to the lock bolt threads and place in the case and pinion shaft. Tighten to 15-30 ft. lbs. (20-41 Nm).
  5. Cover the inside of the differential case with a shop rag and clean the sealing surface of the axle housing and the axle housing cover. Remove the shop rag.
  6. Apply a 1 / 8 - 3 / 16 inch (3.18-4.76mm) wide bead of silicone sealer to the cover.
  7. Install the axle housing and bolts and tighten in a crisscross pattern. Final torque the cover retaining bolts to 28-38 ft. lbs. (38-52 Nm).
  8. Add the appropriate rear axle lubricant to the axle housing to a level 1 / 4 - 9 / 16 inch (6-14mm) below the bottom of the fill hole. If equipped with a limited slip differential, add 4 oz. (118.3 ml) of the appropriate friction modifier.
  9. Install or connect the following:

    Axle housing fill plug and tighten to 15-30 ft. lbs. (20-41 Nm)
    Anti-lock brake speed sensor, if equipped. Tighten the retaining bolt to 40-60 inch lbs. (4.5-6.8 Nm).
    Brake calipers and rotors
  10. If equipped with air suspension, turn the air suspension switch to the ON position.
  11. Road test the vehicle and check for proper operation.
